### ver3.0 zx
|
||||
|
||||
## Description
|
||||
The `lslidar_c16` package is a linux ROS driver for lslidar c16.
|
||||
The package is tested on Ubuntu 16.04/18.04 with ROS kinetic/melodic.
|
||||
|
||||
## Compling
|
||||
This is a Catkin package. Make sure the package is on `ROS_PACKAGE_PATH` after cloning the package to your workspace. And the normal procedure for compling a catkin package will work.
|
||||
|
||||
```
|
||||
cd your_work_space
|
||||
catkin_make
|
||||
```
|
||||
|
||||
## Example Usage
|
||||
|
||||
### lslidar_c16_decoder
|
||||
|
||||
**Parameters**
|
||||
|
||||
`lidar_ip` (`string`, `default: 192.168.1.200`)
|
||||
|
||||
By default, the IP address of the device is 192.168.1.200.
|
||||
|
||||
`frame_id` (`string`, `default: laser_link`)
|
||||
|
||||
The frame ID entry for the sent messages.
|
||||
|
||||
**Published Topics**
|
||||
|
||||
`lslidar_point_cloud`
|
||||
|
||||
Each message corresponds to a lslidar packet sent by the device through the Ethernet.
|
||||
|
||||
### lslidar_c16_decoder
|
||||
|
||||
**Parameters**
|
||||
|
||||
`min_range` (`double`, `0.3`)
|
||||
|
||||
`max_range` (`double`, `200.0`)
|
||||
|
||||
Points outside this range will be removed.
|
||||
|
||||
`frequency` (`frequency`, `10.0`)
|
||||
|
||||
Note that the driver does not change the frequency of the sensor.
|
||||
|
||||
`publish_point_cloud` (`bool`, `true`)
|
||||
|
||||
If set to true, the decoder will additionally send out a local point cloud consisting of the points in each revolution.
|
||||
|
||||
**Published Topics**
|
||||
|
||||
`lslidar_sweep` (`lslidar_c16_msgs/LslidarChSweep`)
|
||||
|
||||
The message arranges the points within each sweep based on its scan index and azimuth.
|
||||
|
||||
`lslidar_pointclou_c16` (`sensor_msgs/PointCloud2`)
|
||||
|
||||
This is only published when the `publish_point_cloud` is set to `true` in the launch file.
|
||||
|
||||
**Node**
|
||||
|
||||
```
|
||||
roslaunch lslidar_c16_decoder lslidar_c16.launch --screen
|
||||
```
|
||||
Note that this launch file launches both the driver and the decoder, which is the only launch file needed to be used.

|
||||
<param name="echo_second" value="false"/>
|
